Popcorn garlands are a thing. I didn't know this until I ran into one at a Christmas gathering with my in-laws. The popcorn has a bit of a toothy quality to it, so there was a drawn out moment of confusion for me, while I tried to figure out where they had gotten so many teeth to make a decoration for the tree. This year, we leaned into it, with the help of my 3d printer.

I got the teeth stl from a toothy cup that caught my eye around Halloween.
